Does anyone know if I will be ok to run my new APS FMIC with out getting it retuned? It is getting really hot here in arizona and I am wanting to get that thing on to compensate for the Heat.... Let me know fellas..


Also I was tuned for the mods in my sig for 22lbs of boost but I turned it down for the summer to 20lbs..

 

anybody/////

 

According to knowledge getting a bigger FMIC is only good for letting you push more power because the temps are lower.. I'm sure you'll be fine if you simply put it on and retune it more aggressive later. That's my advice.

 

It will throw your AFR's off making you run leaner. Retuned needed, but not Dire. Monitor your AFR's

 

How does it throw off your A/F ratio? The ECU will see what the A/F is through the O2 sensors and adjust the fuel input based on MAF signal and temp.

Getting tuned for a FMIC is like getting tuned every time the weather changes 10 degrees....it's pointless.

 

lol thats funny I like that, wouldn't I tend to run leaner anyways sense i was tuned in the winter when it was 70 degrees and nows in the 100's lol...

 

+1 to the guy above me

 

don't bother just sell it to me for 500 shipped

 

ahah i bought it for less. shipped..

 

anybody else before I put this thing on ....

 

Wheres Warrtalon?

 

lol ^^^^ whats that suppose to mean...

 

i am sorry, but that gave me a slight chuckle
go read up on how the ecu works before you give your "expert" advise.

 

consider this.
in colder temps, you can run more boost because your fmic can cool the air charge more effectivley than in hotter temps.
However, in colder temps, you will run somewhat leaner because of the denser air charge. but the ecu slightly compensates for this because of the higher load the maf calculates.

lowering the boost will not necessarily make the car run richer.
It all depends on how it was tunned, not what afr it was tunned to.

 

^^^^ lol.... so can put it on or not Faisal.....
